Solution :
It is given that :
(Null hypothesis, is also correct)
(Alternate hypothesis, also called )
This is a lower tailed test,
Therefore,
Sample proportion,
= 0.04
And claimed proportion, P = 0.05
Significance level, = 0.01
Therefore, calculating the statistics, we get
Standard deviation of
Test statistic,
Now since this is a lower tailed test, p-value =
Rejection Criteria : Reject if p-value < α .
Conclusion : Since the p-value , we fail to reject the null hypothesis. There is insufficient evidence that p is less than 0.05
Answer:
44.49
Step-by-step explanation:
just add all the values
5+9.71+14.1+15.68=44.49
Answer:
x=6/5 or 1.2
Step-by-step explanation:
I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both
2= -5x+8 (next subtract 8 from both sides)
-6= -5x (divide both sides by -5)
-6/-5=x (the negative cancel out next)
6/5 or 1.20 is x
If your original problem should say 2x=-5x+8
2x=-5x+8 (add 5x to both sides next)
7x=8 (divide by 7 on both sides)
x=8/7
